We picked up a couple of 1/64th scale RC cars. These things are really cool. They clip on the side of the TX and charge their nicads for 45 seconds for a full charge... then you can run them for about 4-5+ minutes.

we have verible throttle and steering, forward and reverse.
The TX is is also small, has a antenna that retracts inside the TX on a spool. TX isn't much bigger than a cigarette pack.

The cars are from Japan and are called BIT CHAR-G racers. They're a blast.
